The creators of this movie had to make choices. For viewers who like a artistically well-rounded film, it may have disappointed. The larger "point" to Puncture was to recreate in a microcosm the protracted battle which politically and legally helped expose some of the rampant corruption in the medical supply industry. The actual event was defused by settlement in the early 2000's. The fact that it still strikes a nerve these days is testimony to the work we still need to do in containing the excesses of corruption in the area of commercial health care. It is a reminder of the need for constant vigilance in an arena that too many consumers naively trust.
It's a personal thing, I guess . . . I found it a stylish, well-paced movie with a gripping plot. Like another reviewer, I was more focused on the injustice of the stifling of the invention by corporate power and greed, than wanting a perfectly formed hero and plot resolution. Hey, that's life. It's not usually like a classic movie script. Some of the peripheral characters weren't fleshed out, and the lawyers for the defense were formula villains, but I felt the inventor's helpless rage, Danziger's frustration and fear, and Weiss's alternating disconnection and intensity. If the script was kind of jerky, well, that's the way that Weiss was probably seeing his life go by, and maybe not a bad directorial device.
4 stars for taking on a difficult story that's all too sadly been seen before, and trying it from a different angle.
